INVALID-BED Specification of Letters Patent.

Patented Feb. 9, 1909 Application filed. July 18, 1908. Serial No.444,199.

To all whom it may concern:

Be it known that I, LLOYD W. WARD, a citizen of the United States,residing at Buckhannon, in the county of Upshur and State of WestVirginia, have invented a new and useful Invalid-Bed, of which thefollowing is a specification.

This invention relates to invalid beds, and has for its principal objectto provide a novel form of bed structure in which the various parts maybe readily adjusted for the purpose of enabling the patient to assumeeither a reclining or sitting position.

A. further object of the invention is to provide a means for adjustingand holding the head of the bed frame and that portion of the frameadjacent the head in varying angular positions for the purpose offorming a back rest.

A still further object of the invention is to provide means whereby thehead and foot sections may be adjusted either independently of'eachother or simultaneously and locked in adjusted position.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size and minor details of the structure may be made withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the accompanying drawings :Figure l is a perspective view of a bedconstructed in accordance with the present invention. Fig. 2 is alongitudinal sectional view of the same. Fig. 3 is a detail transversesection of a portion of the bed. Fig. l is a sectional plan View on theline t4.- of Fig. 2. Fig. 5 is a detail view on an enlarged scale of theclamp for locking parts of the bed frame in adjusted position.

Similar numerals of reference are employed to indicate correspondingparts throughoutthe several figures of the drawings.

The bed structure is supported by a main frame comprising a pair ofopposite side standards 10, each of inverted U-shape. The rear legs ofthe standards are connected by an angle bar 11 and the front legs by anangle bar 12, while at the forward portion of the frame is secured arigid portion 13 of the bed bottom, this portion constituting a seatwhen the device is adjusted for use as a reclining chair.

Secured to the inner faces of the front legs are metallic guides 16arranged for the reception of a pair of vertical strips 17 that extendupward from the opposite ends of an angle bar 18. To the approximatelyhorizontal web of the angle bar are swiveled two screws 19 that passthrough threaded openings in the angle bar 12, and the upper ends ofthese screws have milled heads by which the screws may be turned for thepurpose of adjusting the vertical height of the bar 18. This bar 18carries casters or rollers 20 that rest on the floor and byturning thescrews the vertical height of the forward end of the bed may be readilyadjusted.

The head section 25 includes a pair of opposite side posts 26 connectedby cross bars 27 and at the lower ends of the bars 26 are pivoted links28 which extend forward and are pivoted at their front ends on studs 29projecting from the opposite sides of the standards 10. The two bars 26form guides for the reception of a pair of clips or collars 30 which arefree to slide on the bars and the clips or collars carry forwardlyprojecting arms that are pivoted to the rear end of the back section 31of the bed frame, this back section together with the head section beingadjustable to varying angular positions for the purpose of forming areclining chair. Rigidly secured to the side bars of the back section 31are two arcuate bars 33 that are connected at their forward ends by across bar 34-. The bars 33 are provided with arcuate slots that arearranged for the reception of grooved anti-friction rollers 35 and 36,the rollers 35 being supported on suitable hangers 37 depending from thestandards 10, while the rollers 36 are mounted on studs projectingdirectly from said standards. As the anti-friction rollers are spacedapart and the bars 33 are rigidly secured to the back section, therollers will serve to sup port the weight of the back section when thelatter is locked from downward movement.

Extending from the forward bar 34 to the rear bar of the back frame is abar 39, the

forward end of which is curved to follow the are of the bars 33. Thisbar 39 receives a slidable block 40 in the rear portion of which is anangularly disposed recess 41 for the reception of a frusto conicalclamping block 42. The clamping block is arranged near the forward endof a hand wheel rod 43, and the forward threaded end of the rod engagesin a threaded opening that is formed in the block 40, the axis of suchopening being slightly inclined with respect to the opening that isformed for the passage of the bar 39, so that when the rod 43 is turnedin one direction and the screw is forced into its threaded opening, theblock 12 will be car ried against the bar 39 and will serve topositively clamp the bar against one of the walls of the guiding openingin block 40 and thus form a rigid lock between the bar and block andprevent independent movement of either member.

The foot section 50 of the bed is carried by a pair of arcuate bars 51which are rigidly secured to said foot section and which are connectedby a cross bar 52. The bars 51 are provided with arcuate slots for thereception of grooved anti-friction rollers 53 that are carried by plates54: rigidly secured to the inner walls of the front legs of thestandards and bent to follow the angular contour of said legs. To thecentral portion of the cross bar 52 is pivoted a curved link 54', therear end of which is. pivoted on a bolt 55 carried by the block 40, sothat the link forms a connecting means between the back and footsectionsof the bed.

The upper edge of the link 5 1 is provided with a series of lockingnotches 56 for the reception of a latch 58 that is pivoted to a bracket59 on the cross bar 12. On the forward cross bar 11 of the main frame isa bracket 60 carrying a bell crank foot lever 61 that is connected tothe latch by a rod 62 and by depressing the foot lever, the latch may bemoved to release position and if the clamp 42 is then in lockingposition the back and foot sections of the bed may be simul taneouslyrocked for the purpose of lowering the legs and raising the back of thepatient to a more or less erect position, or the two parts may be moveduntil in horizontal alinement with the central or seat section 13 of thebed.

By unscrewing the clamp 4 2 and allowing the latch 58 to remain inlocked position, the back section may be independently adjusted tovarying angular positions without disturbing the foot section, and ifthe back section is then held and the latch released, the foot sectionmay be adjusted independently of the head section, so that the body andlimbs of the patient may be moved independently to the most comfortableposition.

that is claimed is 1. In a bed, a stationary frame, a seat sectionsupported thereby, a head section, links forming a pivotal connectionbetween the stationary frame and the head section, a back sectionslidably connected to the head section, a pair of arcuate bars securedto the back section, guiding means carried by the frame and engagingsaid bars, and means for locking the back section in adjusted position.

3. In a bed, a main frame, a seat section supported thereby, a headsection in cluding a pair of side bars, links connecting the lower endsof said side bars to the main frame, a pair of collars slidable on theside bars, a back section pivotally connected to said collar, a pair ofbars secured to the back section and provided with arcuate slots,antifriction rollers supported by the main frame and extending throughthe slots, and means for locking the back section in adjusted position.
